Sounds just like people wasting their time picking on an old man. You’d have better luck selling on Facebook Marketplace. I had a low mileage GTI clean title that I reverted back to stock and didn’t get a single inquiry from this forum and listed below kbb. Ended up selling to a VW dealer.
The price seems pretty good now considering the upgrades. Especially being a Rabbit edition with 7 speed dsg. It might just take longer to sell as is vs stock.
I don’t see why not maybe the spacing is different for the tips. I can take measurements to see if it would fit. Yeah system doesn’t come with a resonator. Still sounded good though
